Specpoint Systems, LLC manufactures proprietary new instrument systems and replacement parts for Honeywell UVH series ammonia detectors.

SpecPoint UVH20 Ammonia Detector

The Specpoint UVH20 series provides the industry's most reliable and accurate high performance U.V. sensing technology. With over 10,000 systems operating worldwide and exclusive 100% passive sampling, you can monitor up to 8 separate zones with each detector. The UVH20 offers closed or open process sampling with no electrochemical sensor cell to replace.
